The Mystery of Orcival by Emile Gaboriau

A small, fine, chilly rain had succeeded the morning fog; but Sauvresy did not perceive it. He went across the fields with his head bare, wandering at hazard, without aim or discretion. He talked aloud as he went, stopping ever and anon, then resuming his course. The peasants who met him -- they all knew him -- turned to look at him after having saluted him, asking themselves whether the master of Valfeuillu had not gone mad. Unhappily he was not mad. Overwhelmed by an unheard-of, unlooked-for catastrophe, his brain had been for a moment paralyzed. But one by one he collected his scattered ideas and acquired the faculty of thinking and of suffering. Each one of his reflections increased his mortal anguish. Yes, Bertha and Hector had deceived, had dishonored him. She, beloved to idolatry; he, his best and oldest friend, a wretch that he had snatched from misery, who owed him everything. And it was in his house, under his own roof, that this infamy had taken place.

They had taken advantage of his noble trust, had made a dupe of him. The frightful discovery not only embittered the future, but also the past. He longed to blot out of his life these years passed with Bertha, with whom, but the night before, he had recalled these "happiest years of his life. " The memory of his former happiness filled his soul with disgust. But how had this been done? When? How was it he had seen nothing of it? And now things came into his mind which should have warned him had he not been blind. He recalled certain looks of Bertha, certain tones of voice, which were an avowal. At times, he tried to doubt. There are misfortunes so great that to be believed there must be more than evidence.
